I have some abusers on FTP which suck all my 100MBs on the server. How I could stop that from Cpanel or iptables or something else?

I had a similar situation. My situation was resolved in this ServerFault post:

IPTABLES - Limit rate of a specific incoming IP

While I strongly advise you not to use ftp but sftp, you can :

  • Ban offending ip with iptable
  • Use an alternate port so that web bots will take longer to brute force your ftp server.
  • Limit the number or ftp sessions depending on the ftp server you use.
